This invention relates to airv heating means, more particularly adapted to heating large 1 quantities of ai'r,an'd has as one of itsi obj'ects to provicle'an air heating' means that will- 1 utilize the Waste heated gases ofchmmey's to heat the air.

" rangement-inthe chimney will deflect the v heated gases to the next superimposed-secftion thereby providing great efiiciency;

Afurthe'r obj ect of the invention is to provide an'air heating means'thatwill adapt the ornamentations of the chimney to provide a reservoir to arrest the fiowof air and afford "a'certain preheating efiect thereto;

A further object oftheinvention isto provide an air'heating means, contained within ;a chimney, that maybe readily cleaned;

a chimneyof the-customary form, and corn stru'cted of the usual material, such asgbri'clr, as represented in Fig. 1, brother materials a'daptedgfor. the purpose; The illustrationiin Fig. 1 represents a 4 Chimney ofthe larger typeas used to remove gases" from: the boilers of a power plantand theremaining figures also represent chimneys oftheinvention is to pro-j 7 vide an air l1eat1ng 1neans that by ltS' ar- Havin'g reference tothe drawings like numerals referto'like parts throughout the several views, and the numeral'lxrefers to ofthe larger type and while the representa tions aretypicalitqmust be understood that the devi'ce is applicable to smaller'chimneys such as' are usedin-residences or the like.

Where the chimney is adapted for use in connection with boilers, the discharge from the boilers may enterjthrough the orifices 2 shown in Fig. '1, and like orifices ("not shown) I obviously.may be wusedvvith other forms of chimneys. to

As it is a common practicefor ornamentation to provide a moulding 3' around the top of the chimney, this'moulding is takenadvantage- 01": and is constructed hollow to provide a reservoir 4;:Whichby its size withfire lation to "the chimney proper vwill arrestfa I flowof airfentering and passing out there from through pipeshaving less areaiin cross section, and as the wall ,5 ofthechinmeyopv posi'te this reservoir Willbe-warmed from theflue gases, the reservoir will providea pre-heater'ior air therein, 3 V

Connec'tedinto h'sir'servoir are air conductors 6 which may be of varioustypes as' shown, the essential features"thereoi-however consisting of receiving the airjat the flowing gases fromone sectionto theother.

In'Fig. ;6 is'shovvn a modification of this form wherein the sections '8 of the air conductor'are zigzagged in theirdOvvnward path for the] same purpose of interception Whiletheseviews show a continuous con ductor 6 passing' fromthe relatively cooler 9 upper part 9 of the chimney to the relatively hotter lower part lQthereof,inmypreferred form I use transverselypositioned pipesffor, the conductorsections 8, andvvhilethe cross 3 section of pipe'beingcircular is Well adapted These pipes are likewise formed to consti-- tute sections 8 but difler from the continuous conductors mentionedin that they consist of separate pipes imhedded in the walls of tl-ie'chimneyin a-manner to provide a passageway for the air from outside to outside of the 'chimneywalll lVith this arrangement .the reservoir l will i be preferably constructed of an insulated naterial, for. economicalrreasons, although there is no ob ection,toconstruction 213111 that shown and describeditor Fig 1.

In addition a cover l lis constructed which surrounds the chimney, and this cover is separated into compartments 12 by oppositely positioned partitions 13 as shown in Fig.5,

which partitions will direct the air from the uppermost section to the next lower section,

when it will pass through the chimney into an opposite compartment 12 having a like Y partition 13-through which compartmentit will continue downward-to the next lower 7 section to again pass through thechiznney, finally a1- rive at; its point of discharge after repeatedly through the chimney and subjected and continuing in a like manner passin Y to the heat'ot thegases. t t a To snpply this reservoirwith air -a blower 14 or other meansis utilized, which consists preferably of a motor 15 and fan 16., thefan being encased in a housing 1'7 with the housing in turn being connected with a suction pipe 18 adaptedto supply theair to said blower, and feed" pipes 19 will be connected to their destinations.

If'it is desired tohave lower temperature than that'created 1n the to this housing and extend therefrom to the reservoir to supply that member.

The supply may be conducted to the reservoir either outside the chimney aswshown in Fig. 1 and Fig; 6, or-mayb'e extended up hrough the chimney as shown in Figs. 4 and V 5. The latter case is deemed preferable as with the air rising through these pipes withinthe heated gases a more even temperature is provided than when going up the outside, due to the possible effect of climatic conditions. 7

As the'fairconductors areprovided with a continuous'passage'to the pointofdistribution it is obvious that-the blower may be utilized to continue the movement of the air a'he'at of slightly anticipated" leakage in the pipes.

- decreasein velocity, when the air will enter claim said chimney {to the relatii'fely hotter; part air conductors, a' vertical pipe 20 may be connected with the reservoini and extend downward'in a straight lineto be conducted to its-point of discharge in a like manner to that of the conductor and these maybe utilized in combination with theair conductors in if desired as they will absorb less heat in proportion to their relative lengths' In either event by forcing the'air through theconductor 6, andby providing a continuous passageway, the air is "forced downward against the effect of rarefaction and by its rarefaction its velocity will be increased, which mcrea-se in velocity will compensate tor any losses whichm ght occur byan un- Inuse, and assuming'thatt-h'e heated gases are rising the chimney, the blower 14 will be started, when air will be drawn in through the suction pipe 18 to pass through the liousmg 1? of the blower with avelocity created fby the fan lti therein, to dischargewith thesame veloc1ty into the-reservoir, which reservoir, due to its larger ai-ea,'wi11'provid for a T the conductors 6 and from t enon assume the initial velocity, or an increasedvelocity due to rareiaction, land the expansion due tothat rareiaction.
